There are several hydrophobic stretches, such as aa 567-587, that may be transmembrane domains. RetSat is predominantly in the endoplasmic reticulum (ER) where it colocalizes with the ER marker protein disulfide isomerase 5789 763769 1.3.99.23 membrane - 16020 672228 1.3.99.23 membrane associated to 16020 659418 1.3.99.23 additional information perinuclear staining in cells overexpressing RetSat and nuclear staining of endogenous RetSat in primary mouse hepatocytes are observed - 763769
